Dynamical Critical Exponent for Two-Species Totally Asymmetric Diffusion on a Ring [PDF]

open access: diamond, 2010
We present a study of the two species totally asymmetric diffusion model using the Bethe ansatz. The Hamiltonian has $U_q(SU(3))$ symmetry. We derive the nested Bethe ansatz equations and obtain the dynamical critical exponent from the finite-size ...

Lacunarity exponents [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2019
Many physical processes result in very uneven, apparently random, distributions of matter, characterized by fluctuations of the local density over orders of magnitude. The density of matter in the sparsest regions can have a power-law distribution, with an exponent that we term the lacunarity exponent.

Recurrence and Lyapunov Exponents [PDF]

open access: yesMoscow Mathematical Journal, 2003
We prove two inequalities between the Lyapunov exponents of a diffeomorphism and its local recurrence properties. We give examples showing that each of the inequalities is optimal.

Combinatorics of Generalized Exponents [PDF]

open access: yesInternational Mathematics Research Notices, 2018
Abstract We give a purely combinatorial proof of the positivity of the stabilized forms of the generalized exponents associated to each classical root system. In finite type $A_{n-1}$, we rederive the description of the generalized exponents in terms of crystal graphs without using the combinatorics of semistandard tableaux or the charge

Exposure of laboratory animals to small air ions: a systematic review of biological and behavioral studies

open access: yesBioMedical Engineering OnLine, 2018
Background Air ions are molecules of air that have become ionized—that is, they have either lost or gained an electrical charge. Past speculation has suggested that exposure to positive air ions may be harmful to one’s health, while exposure to negative ...

Method of determining the exponent in the formula to predict yielding and maximum capacity under combined stress for bending moment‐resisting joints with drift‐pins

open access: yesJapan Architectural Review, 2023
An engineering judgment is often used to determine the exponent of the verification formula for combined stresses applied to moment‐resisting joints using drift‐pins. In this study, the exponent was determined based on a mechanical model.

Decay of distance autocorrelation and Lyapunov exponents [PDF]

open access: yes, 2019
This work presents numerical evidences that for discrete dynamical systems with one positive Lyapunov exponent the decay of the distance autocorrelation is always related to the Lyapunov exponent.

The dynamic exponent of the Ising model on negatively curved surfaces [PDF]

open access: yes, 2006
We investigate the dynamic critical exponent of the two-dimensional Ising model defined on a curved surface with constant negative curvature. By using the short-time relaxation method, we find a quantitative alteration of the dynamic exponent from the ...

The Oslo model, hyperuniformity, and the quenched Edwards-Wilkinson model [PDF]

open access: yes, 2016
We present simulations of the 1-dimensional Oslo rice pile model in which the critical height at each site is randomly reset after each toppling. We use the fact that the stationary state of this sandpile model is hyperuniform to reach system of sizes $>
